Gary Acord (@gacord on Twitter) wrote to me a pointed out a reference in The Universe Next Door, the first book of Robert Anton Wilson's Schroedinger's Cat trilogy, to the opening of James Joyce's Finnegans Wake.
Joyce: "riverrun, past Eve and Adam's, from swerve of shore to bend of bay, brings us by a commodious vicus of recirculation back to Howth Castle and Environs."
Wilson: "Elverun, past Nova's atoms," the hairy Moon read on to his small circle of admirers, "from mayan baldurs to monads of goo, brings us by a divinely karmic Tao-Jones leverage back past tallchief tactics and aztlantean tooltechs to Louses in the Skidrow Dimehaunts. This way to Humptytheatre."
Moon is Simon Moon, reading from a manuscript "at one of Epicene Wildeblood's wild, wild parties" in the chapter "Louses in the Skidrow Dimehaunts" of The Universe Next Door. Gary tells me it's on page 47 of the one volume omnibus of Schroedinger's Cat. In the original Pocket Books paperback, copyright 1979, it's on page 66.
